Dear Fu Kwun Hwang
Thank you for the Applets, they are excellent! I have used them for teaching
my students about Simple Hamonic Motion and the Principle of Superposition.
Have you done one which shows the motions of particles within a Transverse
Wave and a Longitudinal wave? It would be interesting to look at the
particle motion and compare them within these two wave systems. If it were
possible to show the phase relationship between any of the particles even
better! Showing that any particles that are 2Pi radians out of phase with
each other are 1 wavelength apart is something that students can find
difficult to understand without the help of a moving model.
Once again thank you for all your work.
With best wishes:
Mr.A.E.Vinters.
